Sure, but that's ultimately irrelevant. The survey should be demonstrating choices made by developers, but (web) developers don't have much of a choice when it comes to using JS. Unless you want static HTML, JS is in your stack. In that sense, including JS is rather moot, unless it's exclusively about NodeJS. If it is about Node, then I retract my point.
